To wZZ whom it may concern.-

Be it known that I, WILLIAM J. SCHULTZ, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in Loose-Leaf Binders, of which the following is a description, reference being had to the accompanying drawings, which form apart of my specification.

My inventionrelates to a device for securing any number of loose leaves in book form and which will permit of leaves being withdrawn or added to from time to time, as occasion requires, the object being to provide a device which will not only be simple in con struction, but effective and will firmly hold the desired number of leaves between covers containing my improvement.

The invention consists in providing one cover with a binding post or posts which may be of a determined length or may be of what is knownin the art as a sectional post, so that the length or size of the posts may be increased from time to time, as desired, the posts receiving the leaves, which are provided with perforations at points registering with the posts and a second cover provided with mechanism whereby this cover is clamped onto the binding or leaf receiving posts, which mechanism can only be released by the use of a wrench-key, as will be more fully hereinafter set forth.

In the drawings, Figure 1 is a perspective view of a set of covers with my improvement and showing a number of leaves in place, the whole being shown in book form. Fig. 2 is a perspective view of the casing contained in one of the covers in which the clamping mechanism is held with the top plate of the casing removed to show the interior mechanism.

of Fig. 1 with the key or wrench shown in Fig. 1 withdrawn and a part of the binding or leaf receiving posts shown in full, and Fi .4 is a sectional view taken on the line 4 4 ofFTig. 1.

Like letters of reference indicate identical parts in the respective figures.

A is a cover composed of cardboard or other suitable material, having a suitable binding of leather or canvas or other material used for such purposes, which covering or binding also takes about the casing at the end A and forms the hinge, as at a, for the cover. The casing B, which is preferably made of sheet metal with the bottom, two sides, and end walls, as shown in Fig. 2, has secured in it the The clamping mechanism comprises a plate 1), whose one end is preferably made in the hooded shape, as at I), (see iFig; 2,) within which hood is preferably Q placed a block 0, having a threaded opening therethrough, which opening re isters with openings in the hood'b.

The b ock c is intended'to receive the screw d, which screw also takes through the sides of the hood 1), its other end being squared to receive the wrench-key C, (seeFig. 1,) which key takes through an opening 6 in the end of the casing B. The hooded plate I) is loosely riveted and 1 secured to the bottom of the casin as shown atf. (SeeFigs. 2 and 3.) It is un erstood, of

course, that the plateb is so riveted or secured to the bottom of the casing B as to permit of slight longitudinal play in the casing, which is accomplished by having a slot in the plate I) for the passage of the rivetf, which slot is shown at f. (See Fig. 3.) This plate I) is provided with openings shown at g g, which openings register with similar openings in the casing B. Intermediate of the openings 9 and secured on top of the hooded plate 6 within the casing B by rivets or otherwise is a brace-plate h.

Secured to the side of the casing B at the point by a rivet or other suitable connection is the bowed plate or strip of metal 10, whose free end lies intermediate of the end of the screw cl and the opening g. 1

D represents a second cover composed of cardboard or other material which is suitably bound with leather or canvas or the like. This cover is provided with the leaf-receiving posts E, secured in the usual manner at the end D of the cover, and therefore need not be further described. -These posts have been illustrated as of the sectional typethat is, each section of the post having one end provided with a threaded stud and its other end provided with a threaded socket to receive the stud on the adjacent section. 'The topmost section is preferably provided with a rounded end or cap E to give it a finished appearance. Each section is also preferably provided with openings Z. The purpose of the openings Z in the different sections'of the leaf-receiving posts E is to permit the insertion of a point or other means for screwing or unscrewing the sections, especially after they have become firmly set. In place clamping mechanism, whereby the cover A is retained in place.

ings l I prefer to construct the key C with manner The leaves F, which have perforations at their one end registering with'the posts E, are placed on the cover I) by having the posts E pass through the perforations, and then the cover A, with its clamping a mechanism, is placed on top of the leaves, with the posts E passing through the openings g of the casing B, which is secured to the end of the cover A. In order to retain this cover A in its proper position, the screw d is turned by the Wrench-key C, so as to draw the plate b in the direction of the screw, which will bring the wall of the opening in the opposite end of the plate from the hooded portion against the post E, while the end of the screw (1 will take through the hooded end I) and the block 0, inclosed therein, and bear against the bowed plate is, bringing it into contact with the post E, adjacent the plate is, and thus form what is known as a C-clamp.

The reinforcing-plate h is secured to the bottom of easing B by rivets or pins h,which take through slots in the plate I), as can more clearly be seen in Fig. 3. This permits the plate I) to move independent of the reinforcing-plate h when the screw 01 is operated.

I have illustrated and described what I be lieve to be the preferable construction of my improvement; but of course it will be under stood'that instead of having the blocks cwithin the hooded end I) of the plate I) the hooded end might be made solid, so as to permit of its being threaded in the opening for the screw 01. My reason, however, for making the construction as described with a separate block 0 is that this block may be made of material in which a threaded opening is more readily cut, and so at the same time after the threads should become worn it might readily be replaced without the necessity of replacing the entire plate I), which of course would necessitate the destruction of the rivets whereby the plate I) is held in place and having the same riveted anew, and a number of other minor changes might be made without departing from the spirit of my invention.

What I claim as my invention, and wish to secure by Letters Patent, is-

1. A loose-leaf binder comprising a set of covers, the one provided with leaf-receiving posts, the other provided with a casing in its one end having openings registering with said posts, a plate provided with a block at its one end having a screw-threaded opening there through, said plate being adjustably mounted within said casing, said plate adapted to fit about the posts, a threaded rod taking into the threaded opening of said block on said plate and adapted to be controlled from the outside of the casing whereby upon its operation the walls of the openings in said plate are brought into frictional contact with said posts.
